I lost my interest after the video. Made for on/over ear headphones. Hiss with iems. Still not powerful enough like M8. I will pass, M8 is a winner for me. They have nice touches indeed but no good for me.

There is no digital output on the Theorem 720 DAC. I think Cypher Labs has a lot of faith in its performance as a DAC, and thus made the choice (to save space and perhaps battery life) to forgo a digital output.

Was that balanced output just for headphones or was it was balanced connector to amplifier as well?

The dedicated line out is rated at 2.1vrms, and is single-ended. I believe the balanced output is intended only for headphones.

If I find out different, I'll let you know.

Battery life and a small charger, plus all the different cables supplied are great points.

The headphone output's output impedance is actually below 1 ohm. The issue I have with sensitive in-ears and the Theorem 720 DAC is its noise floor.

Regarding the battery life and small charger: yes, huge positive points for it.

Although, Jude, I feel they should take a leaf out of Centrance's book in offering their M8 and M8LX. I'm an Apple user and feel that part of the high USD899 price goes towards the Android part that I will never use.

I have the Solo-R and I wish they had improved on that by having a built-in amp with longer than even the current 14 hours. Call it a Duo-R! I'd pay USD699 for that.

So I use my Solo-R at home with a myriad of amps but for on the road, I use my newly-acquired ADL X1.

After we shot this video, I realized I neglected to mention the very cool Alpha Design Labs X1when mentioning USB/iDevice DAC/amp combos. There are so many things I like about the ADL X1, and its design (with the sample rate indicators, for example) is superb. However, like the Theorem 720 DAC, I find the X1's headphone output's noise floor too high for sensitive in-ears, and the X1 doesn't seem to me to have anywhere near the output power of the Cypher Labs Theorem 720 DAC. (The X1, however, is priced at just over half the Theorem 720 DAC.)

Hi, David here from Cypher Labs. The Theorem 720 DAC is our newest product, which took over two years of development. Production quantities will begin shipping late next week through the second week of September. Please be patient with our dealers as we work to get product into your hands.

I know you all will be asking about specs, so I thought I would just post them here so you can find them in one place. These are on our website too of course http://cypherlabs.com/

I love my ADL X1 when I'm outside the house and the noise floor doesn't bother me because firstly I don't use IEMs and restrict myself to either a Sennheiser PX200 or Sony DRZX701iP where the ADL has sufficient power.

Here's another cool thing about the ADL X1. In fact I believe it is the only iDevice DAC/amp that can do this. If you are using a iPhone as your source and you use the supplied 4-ring 3.5mm cable because you know you are expecting a lot of phone calls, say in the next hour, you can make and receive calls if your headphone has a mic. You will of course then be not using the built-in DAC but as I said, sometimes you know the calls are just coming in but you still want good music.

Oh and if you hold an X1 in your hands the first time, you'd swear it was a dummy set. It is unbelievably light.
